Abstract
The invention provides a method of making a biological disc graft. In one embodiment, the biological disc graft is useful for treating back or neck pain. In one embodiment, the biological disc graft is useful for treating any joint pain. The invention also provides a method of implanting said biological disc graft in a way that is minimally invasive and less dangerous.
Claims14
A minimally invasive method for implanting a biological disc graft to treat back or neck pain, the method comprising:
- providing a biological disc graft comprising a first and a second bone endplate, a fibrocartilage layer positioned between the first and the second bone endplate, wherein the fibrocartilage layer and the bone endplates are sourced from a pubic symphysis joint, and wherein the bone and fibrocartilage layer are decellularized;
- making an incision in an annulus fibrosus of an intervertebral disc;
- removing a volume of nucleus pulposus equal to a volume of the biological disc graft;
- and
- inserting the biological disc graft into the space previously occupied by the volume of nucleus pulposus.
A method for the total replacement of an intervertebral disc using a biological disc graft, the method comprising:
- providing a biological disc graft comprising a first and a second bone endplate, a fibrocartilage layer positioned between the first and the second bone endplate, wherein the fibrocartilage layer and the bone endplates are sourced from a pubic symphysis joint, and wherein the bone and fibrocartilage layer are decellularized;
- removing an annulus fibrosus and nucleus pulposus of the intervertebral disc;
- removing cartilaginous endplates of vertebral bodies above and below the intervertebral disc;
- and
- inserting the biological disc graft into the intervertebral disc space;
- wherein the bone endplates of the biological disc graft are seated in the space previously occupied by the cartilaginous endplates.
A method for the total replacement of a joint using a biological disc graft, the method comprising:
- providing a biological disc graft comprising a first and a second bone endplate, a fibrocartilage layer positioned between the first and the second bone endplate, wherein the fibrocartilage layer and the bone endplates are sourced from a pubic symphysis joint, and wherein the bone and fibrocartilage layer are decellularized;
- removing cartilaginous endplates of bones above and below the joint;
- and inserting the biological disc graft into the joint space.
